Explanation:

President Roosevelt was in office when Pearl Harbor happened, and it was the perfect ocassion that the government of the United States needed to enter a war that was clearly being won by the Germans and Japanese, they had already taken decision prior to this to help the allies, but they couldn´t directly send troops, when the bombings on Pearl Harbor took place, and since USA had never provoked, attacked or done anything to upset Japan, they were now able to declare war on Japan an its allies.
